ED STATES PA E T FF 153E? WILLIAM E. HALE, OF PHILADELPHIA, PENNSYLVANIA,ASSIGNOR TO B. H. BEAUMONT COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA.

To all whom itjmay concern;

Be it known that I, WILLIAMFE. IIALE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Means for Operating Overhead Valves of Coaling Apparatus, of which the following is a specification.

One object of my invention is to improve the means for operating the bunker gates of an overhead storage system used in connection with lorries for discharging coal or other fuel from the bunker to the hoppers of stokers connected to boilers, or other furnaces. I

.A further object of the invention is to prevent; the duplication of the'operating mechanism of the several gates and to'provide a single device carried by the traveling lorry, which device is in operative position when'thelorry is under'a given bunker discharge opening f In the accompanying drawings Figure l, isa side view of a coal handling apparatus showing the bunker in section and. the gate operating mechanism on the lorry clear of the gate connections;

Fig. 2, is a front elevation of the device illustrated in Fig. 1;

Fig. 3, is a perspective view of one of the gates and its connection;

Fig. 4:, is a perspective view of the mechanism carried by the lorry;

Fig. 5, is a diagrammatic view, showing the hook in engagement with the gate bar, the gate being in the closed position;

Fig. 6, is a view, showing the hook in engagement with the bar and the gate in the extreme open position; and

Fig. 7 is a side view of the hook.

Referring to the drawings, 1, 1 are the overhead beams supported in any suitable manner, and on these beams are rails 2. 3 is the lorry structure having axles 4: on which are mounted wheels 5 which travel on the rails 2. The lorry structure consists of a frame 6 made of angle irons, or other metal shapes and arranged to support the hopper 7 having one or more chutes 8 arranged to discharge, in the present instance, into the magazine of a boiler furnace. It Wlll be understood that the shape of the lorry and the particular structural work of the frame may be modified without departing from the essential features of the invention.

- MEANS FOR OPERATING OVERHEAD VALVES OF GOALING- APPARATUS.

Specification of Letters Patent. Patented July 9, 1918, Application filed December 5, 191% Seria1No;2o5,52O.

The invention relates particularly to the means on the lorry for operating the gates of the bunker. 9 is the bunker, supported on any suitable structure, and 11 is a casing forming one of the bunker discharge openings. The casing has a curved end and adapted to close the opening is a curved gate 12 which is pivoted at 13 to the casing and has arms'lt to which are attached the bars 15, one on each side of the gate in the present "instance. The bars are supported on a bar 16'carried by a fixed hanger 17 in close proximity to the gate.

I Two rods 10 and 18 connect the outer ends of thebars 1'5 and these rods are in position to be engaged by a hook 19 on a shaft 20 adapted to a'bearing 21 mounted on the lorry frame and on the shaft 20 is a bevel pinion 22, which meshes with a bevel pinion 23 on a vertical shaft 24 adapted to bearings 25 on the "lorry frame and'having at its lower end an operating handle 26. On turning this handle, the vertical shaft 24 and the horizontal shaft 20 are turned and the hook moves from the position illustrated in Fig.1 to a position illustrated in Fig. 6,

opening the gate to its full extent.

It will be noticed that when the hook is in the position illustrated in Fig. 1, it is clear of the gate rods 10 and 18, so thatthe lorry frame can be moved on its rails without the hook coming in contact with any of the operating mechanism, but when it is desired to open a given gate, then the hook is moved in the position shown in Fig. 5, in engagement with the rod 18, the gate being still closed. On moving the hook to the position shown in Fig. 6 it engages the rod 18 and moves the gate 12 to the open position and the coal, or other material, is allowed to flow from the bunker into the lorry, and by reversing the movement the hook l9 presses upon the rod 10 and forces the gate into the closed position. Thus it will be seen that a single operating device carried by a lorry structure can actuate the several gates of a bunker, so that all suspending devices at the several gates are dispensed with.- This is particularly advantageous in boiler rooms where the space is cramped to a certain degree, and where the gate operating devices are liable to interfere with other mechanism.

The book 19 is made as shown in Figs. 4,
